22. PARAMETERS
Pr.65
-
Pr.69
This parameter should be set to automatically
restart the inverter to continue operation by reset-
ting it if an inverter alarm occurs. 'OPT is dis-
played during retry.
a
CAUTION
When the retry function has been selected,
keep away from the motor and machine
unless required. They will start suddenly (after
a
predetermined
time
has
passed)
at
occurrence of an alarm.
When the retry function has been selected,
apply the accessory CAUTION seal to a place
where it is easlly identifiable.

It is possible to know the total number of success of the retry for restart by reading Pr.69. If
range of 0.1 to 360 seconds.
"0"
is set, the accumulated count is cleared.
Notes:
1. The inverter automatically restarts the operation after the retry waiting time Set for
Pr.68. Therefore, if the retry function is used, pay suffcient care so that restarting
of the inverter wiii not constitute hazards to the operators.
2. In the inverter reset operation by the retry function, the accumulated data of
electronic thermal relay and regeneration brake duty ratio,
etc. is not cleared.
This reset is different from the power reset operation.
